Hydrostatic pressure testing equipmemt used for plastic pipes according to ISO 4427
Ⅰ. Outline:
Hydrostatic pressure testing equipmemt used for plastic pipes according to ISO 4427 is suitable for the determination of the damage resistance time of thermoplastic pipes under the condition of instantaneous hydraulic blasting of pipes and long-term constant pressure. It is an indispensable testing instrument for scientific research institutes, quality inspection departments and pipe manufacturers. The hydrostatic testing machine uses computer embedded control. Modular design for individual control. If there is a problem in any way, as long as the stop valve of the current station is closed, it will not affect the normal operation of other stations. It has pipe rupture identification, real-time monitoring, call data recovery, printing, storage test results, sample pre-processing settings. Such functions, and according to the needs of national holidays, can store up to 7 days of data. The machine is widely used in internal pressure-resistance tests of various plastic pipes .It is an ideal testing equipment for building materials industry ,pipe manufacturing factories ,national inspection departments and scientific research departments.
Ⅱ. System Feature:
1. Industrial tablet control, direct control.
2. The machine with "precision pressure control unit" multi-channel combination.
3. Each station is independently controlled no interference.
4. 5-statiions, 10-stations, 15-stations, 20-stations and other multi-station optional, up to 60 stations and above. With a hydrostatic test, blasting test.
5. Max. pressure: 10,16,20, 30MPa ...
6. Pipe diameter range: Φ16 ~ 2000mm can customized.
7. Perfect test system on the burst, pressure maintaining, pressure relief, overvoltage, operation, the end of the leak, rupture eight test states to make accurate analysis and judgment, with real-time monitoring, data storage.
8. Power protection, test report storage / print output and other functions. Automatically determine the effective time, invalid time, the remaining time and other parameters, to prevent the evening, holidays and other periods of failure time, invalid time.
9. When power-down time ensure that the test is accurate and smooth completion. Instrument structure is reasonable, stable performance, easy operation, display intuitive.
10. Rich software interface (multi-language environment to meet customers in different countries and regions.
Ⅲ. Meet standards
